  • Just picked up a second hand Dura Ace FC7710 NJS Crankset.

    With regards to suitable BB's I ideally would like a sealed one as I will be using this outside in all weathers. Condor Cycles said that the only option is a Dura Ace BB which do not have seals (as far as I know).

    Do I have any other options?
    Or is it ok to run a DA BB in the wet?
